Idaho Mortgages Overview

Idaho real estate has been a bit more expensive than the rest of the country in recent years. The median home value in the state is $369,300, while the national median is $281,400.

Most counties in Idaho have a conforming loan limit at the standard $726,200 However, Blaine and Camas counties have a limit of $740,600, while Teton county has a limit of $1,089,300. This is a reflection of the higher average real estate prices in those counties. FHA limits in Idaho mostly stick to the typical $472,030 limit, with a handful of exceptions.

Idaho is a deed of trust state, meaning when you take out a home loan in the Gem State you’ll likely get a deed of trust instead of an actual mortgage. Lenders who issue mortgages have to go to court to foreclose on the home that the mortgage applies to. But if a trust deed is offered instead, a lender can initiate a power of sale foreclosure by hiring a third party to auction the home it wants to sell, bypassing the court process.

Idaho has some lax disclosure laws for sellers, so it’s important that buyers be vigilant when considering a property purchase. The best course of action is to arrange a property inspection with a well-trusted inspector or company. This is particularly critical when disclosure laws are not as strict as they are in other states, as is the case with Idaho.

30-Year Fixed Mortgage Rates in Idaho

Fixed-rate mortgages are the tried-and-true home loan option for buyers. For people who plan to stay in their new home for a considerable period of time, a fixed-rate mortgage may be especially attractive. The most common type of home loan is a 30-year fixed-rate mortgage. With this mortgage you have three decades to pay off the loan and the interest remains the same for the duration of that period, unless you refinance. Another option for Idaho buyers is a 15-year fixed rate mortgage. This loan comes with a lower interest rate but the monthly payments are higher.

The average rate for a fixed 30-year mortgage in Idaho is 6.31% (Zillow, Feb. 2023).

Idaho Jumbo Loan Rates

Idaho homes are less expensive than the average U.S. home, so it makes sense that the conforming loan limit is about average in almost the entire state. A jumbo loan is a loan that exceeds the respective county's conforming loan limit. For example, this could be a $800,000 loan in Gem County, where the limit is $726,200. These oversize loans are accompanied by higher interest rates. Banks take on a bigger risk when issuing large loan. The higher interest is meant to offset that risk.

The average 30-year fixed jumbo loan rate in Idaho is 6.25% (Zillow, Feb. 2023).

Idaho ARM Loan Rates

An adjustable-rate mortgage (ARM) stands in contrast to a fixed-rate mortgage. Unlike a fixed-rate mortgage, an ARM’s interest rate can “adjust” or change over the period of the loan. Typically an ARM will offer a lower introductory interest rate as compared to a fixed-rate mortgage. That initial period lasts somewhere between one and 10 years. At the end of that period, the interest rate will usually rise. The terms of the loan will spell out how many times the rate can rise and the highest possible level that it can reach.

The average rate for a 5/1 ARM in Idaho is 5.88% (Zillow, Feb. 2023).

Idaho Mortgage Resources

Idaho Mortgage Taxes

As an Idaho homeowner, you’re allowed to deduct mortgage interest on your state income tax as well as your federal income tax. The Idaho rules for state itemized deductions generally follow suit with federal rules. In Idaho, there is also no tax charged on real estate property title transfers.

Idaho Mortgage Refinance

If you’re refinancing your Idaho mortgage, there are some options to get you started. First, you don’t have to work with the lender who issued your original mortgage (though you can certainly do this). Feel free to shop around and compare refinance lenders to figure out what works best for your particular situation.

While the Home Affordable Refinance Program (HARP) no longer exists, there is an alternative: the High Loan-to-Value Refinance Option from Fannie Mae.

The Idaho Housing and Financing Association also works with homeowners on refinancing their loans.
